Summer in Hixson brings plenty of opportunities to enjoy everything the Chattanooga area has to offer. Whether you’re shopping and dining around Vinterest Antiques, spending the day at the Tennessee Valley Railroad Museum, attending community events throughout Hamilton County, or enjoying time with family around the Tennessee River, warm weather is a welcome part of the season.
However, East Tennessee summers can also bring prolonged periods of heat and humidity. When temperatures rise and moisture levels in the air increase, your body has to work harder to stay cool. Without proper hydration and precautions, heat-related illnesses can develop quickly and become serious.
Understanding the difference between heat exhaustion and heat stroke can help you recognize symptoms early and know when to seek medical attention. If you’re experiencing dizziness, fatigue, dehydration symptoms, or other heat-related concerns, AFC Urgent Care is here to help. Our walk-in clinic provides convenient same-day care with no appointment necessary, although online check-in is recommended to help reduce wait times.

Understanding Heat-Related Illnesses
Your body naturally regulates its internal temperature through sweating. As sweat evaporates from the skin, heat is released, helping maintain a safe body temperature even during warmer weather.
Problems can occur when high temperatures, humidity, physical activity, or dehydration overwhelm this cooling process. When the body struggles to cool itself effectively, heat-related illnesses may begin to develop.
Heat exhaustion and heat stroke are among the most serious forms of heat illness. Although they share some symptoms, they differ significantly in severity. Heat exhaustion is often treatable when addressed promptly, while heat stroke is a life-threatening emergency requiring immediate medical intervention.
Recognizing the warning signs of both conditions is one of the best ways to protect yourself and your family during Tennessee’s hottest months.
What Is Heat Exhaustion?
Heat exhaustion occurs when the body loses excessive amounts of water and electrolytes through sweating. As fluid levels drop, the body’s ability to regulate temperature becomes impaired, leading to symptoms that can worsen if left untreated.
In Hixson and surrounding communities, heat exhaustion frequently affects outdoor workers, athletes, delivery drivers, festival attendees, and anyone spending extended periods outside during hot weather.
Unlike heat stroke, heat exhaustion often develops gradually. Early symptoms may seem mild at first but can progress quickly if a person continues physical activity or remains in the heat.
Fortunately, prompt cooling, hydration, and rest can often reverse heat exhaustion before it becomes more serious.
Common Symptoms of Heat Exhaustion
Heat exhaustion symptoms can vary from person to person but often include:
- Heavy sweating
- Cool, pale, or clammy skin
- Dizziness or lightheadedness
- Headache
- Nausea or vomiting
- Muscle cramps
- Weakness or fatigue
- Excessive thirst
- Rapid but weak pulse
- Difficulty concentrating
- Fainting
Many people initially assume they are simply tired or dehydrated. However, continuing outdoor activities without treatment can increase the risk of heat stroke.
What Is Heat Stroke?
Heat stroke is a medical emergency. Call 911 immediately.
Heat stroke occurs when the body’s temperature control system fails and core body temperature rises to 104°F or higher. At this stage, the body can no longer cool itself effectively, creating a dangerous situation that requires emergency medical care.
Heat stroke can damage major organs, including the brain, heart, kidneys, and muscles. The longer treatment is delayed, the greater the risk of serious complications.
Although heat stroke may develop from untreated heat exhaustion, it can also occur suddenly during strenuous activity in hot conditions. Athletes, outdoor workers, and individuals participating in summer events may be particularly vulnerable.
Heat stroke should always be treated as a medical emergency.
Common Symptoms of Heat Stroke
Warning signs of heat stroke include:
- Body temperature of 104°F or higher
- Hot, flushed skin
- Little or no sweating
- Rapid, strong pulse
- Severe headache
- Nausea and vomiting
- Confusion
- Agitation
- Slurred speech
- Loss of coordination
- Seizures
- Loss of consciousness
One of the most important warning signs is a change in mental status. If someone becomes confused, disoriented, or unresponsive after heat exposure, immediate emergency care is necessary.
How Can You Tell the Difference Between Heat Exhaustion and Heat Stroke?
Although both conditions are caused by overheating, there are several important differences that can help identify which condition may be occurring.
Body Temperature
People experiencing heat exhaustion typically have a body temperature below 104°F. Heat stroke is characterized by a core body temperature of 104°F or higher.
Skin Appearance
Heat exhaustion often causes cool, moist, and clammy skin because sweating continues. Heat stroke commonly causes hot, red skin and may involve little or no sweating.
Mental Status
Individuals with heat exhaustion generally remain alert despite feeling weak or dizzy. Heat stroke affects the brain and nervous system, leading to confusion, unusual behavior, slurred speech, or loss of consciousness.
Urgency of Treatment
Heat exhaustion should be treated promptly and evaluated by a medical provider if symptoms persist. Heat stroke requires immediate emergency medical attention and a call to 911.
If you’re unsure whether symptoms require medical evaluation, visiting an urgent care near you can provide answers and help prevent complications.

How Heat Exhaustion Progresses into Heat Stroke
Heat exhaustion often serves as the body’s final warning sign before heat stroke develops. Without adequate cooling and hydration, body temperature can continue to rise until the body’s natural cooling mechanisms become overwhelmed.
Several factors increase the likelihood of progression, including:
- High humidity
- Prolonged sun exposure
- Outdoor work
- Athletic training
- Heat waves
- Inadequate fluid intake
Treatment for Heat Exhaustion
If heat exhaustion is suspected:
- Move indoors or into a cool environment
- Rest and stop physical activity
- Drink cool water or electrolyte beverages
- Remove excess clothing
- Apply cool compresses or take a cool shower
Seek medical attention if symptoms fail to improve or worsen.
Treatment for Heat Stroke
Heat stroke is a medical emergency.
Call 911 immediately and begin cooling efforts while waiting for emergency responders. Move the person into shade or air conditioning, remove excess clothing, and apply ice packs or cool towels to the neck, armpits, and groin.
Prevention Tips for Hixson Summers
Most heat-related illnesses can be prevented with a few simple precautions.
- Stay hydrated throughout the day.
- Schedule strenuous outdoor activities during cooler morning or evening hours.
- Wear lightweight, breathable clothing.
- Take frequent breaks in air-conditioned environments.
- Gradually adjust to hotter temperatures.

- Monitor older adults, young children, athletes, and outdoor workers closely during extreme heat.
Knowing when to visit urgent care for dehydration or heat-related symptoms can also help prevent serious complications.
